Yes .. open the files with some program that will view them, e.g.
Notepad, Wordpad, Word, or any specialty viewer. You can look at any
file, most of the time. However, depending the the printer driver that
created these files, you may see gobbleygook or you'll see something
that makes sense to you. There is nothing standard about output from
printer drivers. All it is is something saved to a file rather than
being send to the printer.
Being able to view the files may not be useful to you. Why do yo want to
do this? What are your expectations?
THe only thing I can think of is that the file might give you a clue
about what "language" the printer instructions are in, e.g. HP's PCL, or
PostScript, or whatever.
Hope this is useful to you. Let us know.
